PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 585,576, dated June 29,1897. Application filed December 11, 1896. Serial No. 615,311. (Nomodel.)

To all whom it may concern.-

Be it known that 1, ALEXANDER J. HOOD,

a citizen of the United States, residing at Muscoda,in the county ofGrant and State of WViscousin, have invented certain new and usefulImprovements in Printing-Presses; and I do hereby declare the followingto be afull, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to improvements in attachments forprinting-presses.

The object of the invention is to provide an attachment of the charactermentioned which is adapted to be employed with the ordin aryconstruction of presses andis designed for inking the form of apress,whereby a variety of colors may be printed at a single impresslon. 7

With this objectin view the invention consists, substantially, in theconstruction, combination, and arrangement of parts which willhereinafter fully be illustrated,described, and claimed.

In the accompanying drawings, Figure 1 is a perspective View of aportion of a printingpress having the herein-described attachmentapplied thereto. Fig. 2 is an enlarged detail perspective Viewillustrating the attachment removed from the press.

Similar numerals of reference designate corresponding parts in thefigures of the drawings.

Referring to the drawings, 1 designates the bed of a press; 2, theinlcdisk; 3, the rollercarrying frame, and 4 the rollers thereof.

The improved attachment is adapted for connection to the roller-carryingframe 3, and consists of a pair of arms 5, the outer ends of which arepivoted beneath the ink-disks 2 of the press, so as to provide arigidconnection between the said arms 5' and .the bed of the press and whichwill admit of the arms 5 having an upwardly-swinging movement, and theother ends of said arms 5 are each provided with an elongated slot 6 fora purpose to be presently stated.

Secured to the forward ends of the arms 5 and extending across the bedof the press is a carrying-frame 7, which carrying-frame is designed tohave secured therein by any suitable means a series of independentink-pads 8, the latter being of varying colors, so as to apply the inkto the form carried in the bed 1. Formed on each end of the frame 7is anoutwardly-projecting stud 9, said studs being screw-threaded and havingmounted'thereon thumb-nuts 10. The studs 9 are adapted to be inserted inthe slots 6 of the arms 5, and by means of the nuts 10 said studs may beheld at any point throughout the length of the slots 6, therebyproviding for the proper adjustment of the frame 7, carrying the pads 8,with relation to the type of the form.

For connecting the arms 5 with the rollercarrying frame 3 links ll arearranged at each side of the bed 1, and the upper and lower ends of saidlinks are pivotally secured to the arms 5 and the frame 3, whereby freemovement of said links is insured and the operation ofvthe arms 5effected.

The operation of the herein-described attachment is clearly apparent tothose familiar with the art, and when desired for use the desiredcolored pads 8 are placed and secured within the carrying-frame 7. \Vhenthe press is in operation and the frame 3 swings upward and downward, itwill be seen that the arms 5, through the medium of the links 11, arealso given an upward and downward swinging movement, the pivot at theouter end of said arms permitting such a result. By reason of thisupward and downward swinging movement of the arms 5 the pads 8 in thecarrying-frame 7 will be alternately brought into contact with the formin the bed land out of contact therewith. The pads 8 may be of anyapproved construction, and when forced against the form on the bed willimpart to such form the desired colors at given points throughout thesame, so that a distribution of the various colors will be eifected at asingle impression.

By employing proper bearers, which are adapted to carry the rollers 4over the type where colors are desired, the main body of the type may beinked with the rollers while the portion inked by the pads 8 will beunaffected by said rollers. This highly desirable and advantageousresult over the ordinary manner of printingin colors can be accomplishedin a shorter period of time than any such ordinary method, and it willalso be noted that the distribution of the colors may be so regulated asto be placed at any position on the form, it only being necessary tohave the carrying-frame 7 of a size corre sponding to the chase and toplace the inkpads in said carrying-frame in such positions as willcorrespond with the parts of the form it is desired to distribute thecolors upon.

The attachment may be applied to different forms of presses, and I donot wish to limit myself to any particular one, and it will also beunderstood that the invention is susceptible of changes in the form,proportion, and minor details of construction Which may be resorted towithout departing from the spirit or sacrificing any of the advan tagesof the invention.

Having thus described the invention, what is claimed as new is- 1. Anattachment of the class described, comprising a plurality of armsadapted to be suitably pivoted to the bed of a press, a carryin g-frameconnected to said arms and adapted to have secured therein a pluralityof inkpads of varying colors, a roller-carryin g frame also pivoted tothe bed of the press, and means for connecting said arms with theroller-carrying frame, whereby at the operation of said frame theink-pads are adapted to be brought alternately into and out of contactwith the form to print a variety of colors at a single impression,substantially as described.

2. An attachment of the class described, comprising a plurality of armsadapted to be pivoted to the body of a press, each of said arms beingprovided in one of its ends with an elongated slot, a frame carried bysaid arms and provided with outwardly-projecting studs adapt-ed to beseated and secured in said slots, said frame being further adapted tohave secured therein a plurality of inkpads of varying colors, and linksconnecting said pivoted arms with the moving parts of the press, wherebythe ink-pads are adapted to be alternately brought into and gnoved outof contact with the form at the operation of said parts, and a varietyof colors printed at a single impression, substantially as described.

3. An attachment of the class described, comprising a plurality-of armsadapted to be pivoted to the body of a press, each of said arms beingprovided in one of its ends with an elongated slot, a frame carried bysaid arms and adapted to have secured therein a plurality of ink-pads ofvarying colors, out- Wardly-projecting, studs formed on the ends of saidframe and adapted to be seated in the slots of the pivoted arms, meansfor securing said studs in said arms to retain the studs at differentpoints throughout the length of the slots, and means for connecting thepivoted arms with the moving parts of the press, whereby the ink-padsare adapted to be alternately brought into and moved out of contact withthe form at the operation of said parts, and a variety of colors printedat a single impression, substantially as described.

4. An attachment of the class described, comprising a plurality of armsadapted to be pivoted to the body of a press, each of said arms beingprovided in one of its ends With an elongated slot, a frame carried bysaid arms and adapted to have secured therein a plurality of ink-pads ofvarying colors, out- Wardly-projecting studs formed on the ends of saidframe and provided with screw-threads, thumb-nuts mounted on saidthreaded studs, said studs being adapted to be seated in the elongatedslots of the pivoted arms and to be secured therein by said thumb-nuts,and links connecting said pivoted arms with the moving parts of thepress whereby the ink-pads are adapted to be alternately brought intoand moved out of contact with the form at the operation of said partsand a variety of colors printed at a single impression, substantially asdescribed.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
